UI Fixes and Playback Improvements
Release Date: June 2, 2026
Type: Bug fix and improvement release
What's New
Show W unit on panels toggle
A new toggle in Settings lets you hide the "W" or "kW" unit suffix on panel cards, showing just the number. Saves space on smaller screens where the unit label pushes the number into a smaller font or wraps unexpectedly.
Half-speed playback
The timeline speed button now cycles 0.5x, 1x, 2x and defaults to 0.5x. The slower starting speed makes it easier to follow what happened across the day without scrubbing too fast.
What's Fixed
Last Reported showing relative time
The panel detail modal was showing "Last Reported" as a relative duration ("5 days ago") calculated against the current clock. When viewing historical data this was misleading because the relative label was computed from now, not from the selected time. It now shows an absolute timestamp (e.g. 6/2/2026 11:49 AM) in both live and historical modes.
Time slider not tracking the sun ball
The slider was spanning the full 24-hour day while the arc only displayed the dawn-to-dusk window, so the slider handle and the sun ball position were never aligned. The slider now spans the same compressed window as the arc. Jump-to-start and playback also begin at dawn instead of midnight.
Layout editor drag placement
Panels were always placed by their top-left corner regardless of where on the card you grabbed them, but the drag ghost did not reflect this, making it hard to predict where a panel would land. The ghost image now anchors to the top-left corner so what you see is what you get. The instruction text was updated to explain this behavior and increased in size for readability.
Drop targets invisible against orange panels
The drop target highlight in the layout editor was a subtle orange tint that was nearly impossible to see against the warm orange panel color scheme. It is now a bright blue outline that is clearly visible regardless of panel brightness or color.
Battery mode displaying in ALL CAPS
The battery operating mode label was showing raw sensor strings in all caps ("SELF CONSUMPTION", "TARIFF OPTIMIZER"). Mode strings are now converted to title case ("Self Consumption", "Tariff Optimizer"). This is a generic conversion that works for any battery integration, not just SunPower.
A small "(operating)" label with a tooltip was also added to clarify that this field shows the current firmware state, which can differ from the configured Battery Control Mode in HA. For example, TARIFF_OPTIMIZER appearing when you have configured Self Supply is normal behavior: the firmware enters this holding state when the battery hits 100% or the reserve floor, and returns to the configured mode once SOC moves away from the limit.
Sun arc improvements
Dawn and Dusk markers now have a tick line that straddles the horizon, pointing up into the arc and down toward the label, making it clearer where each event falls on the timeline. Sunrise and Sunset reference lines are now solid and extend from the label text all the way to the horizon instead of starting at the arc point.
No settings migration needed. Update via Settings > Add-ons > Solar Sentinel > Update, then do a hard refresh (Ctrl+F5) to clear cached JS files.
